Set a number of installation directories in tqt3.SlackBuild to install tqt3/tqtinterface to TDE installation directory to create what I feel is a more compact and logical tree:
/opt/tde
├── bin
├── include
│ └── tqt
│ └── private
├── lib64
│ ├── pkgconfig
│ ├── tde
│ │ └── plugins
│ │ ├── designer
│ │ └── styles
│ └── tqt
│ ├── mkspecs
│ └── plugins
│ ├── crypto
│ ├── designer
│ ├── inputmethods
│ ├── integration
│ └── styles
└── share
└── tqt
└── translations
